This supplemental manual provides instructions and infamation fcr an all-electric

governor that replaces the combination electric-hydraulic governor which is covered

in your Generator Set, Operation and Maintenance Manua I.

This all~lectric governor system is currently being installed on all 60 and 90-KVA ..

engine-driven generator sets.

Description

The alI* lectric system was selected for control of engine speed (and generator output

frequency) because of its maintenance free operation, dependability, and because it

provides faster engine response to load changes and therefore closer generator frequency

control. Refer to the American Basch Handbook, which accompanies this manual, for

adetailed description. A brief description is given below:

The governor system consists of the following main components:

Magnetic pickup

Control unit

Actuator

A.

B.

C.

Magnetic Pickup

The magnetic pickup (Fig. 1) is a device fa detecting the speed of the engine.

It is mounted in the flywheel housing directly over the ring gear. It produces an AC

signal to the control unit when the ferrous flywheel teeth pass through the magnetic

field at the end of the pickup.

Control Unit

The control unit (Fig. 1) is a box containing a compact assembly of solid state

components. It receives an AC signal from the magnetic pickup and senses speed

changes in the engine. It provides a voltage signal to the actuator which causes the actuator to move the fuel control lever as required to maintain a predetermined

engine speed. Its power is received from the 12-V DC battery system.

Actuator

The actuata (Fig. 1) supplies the fcrce needed to move and. posit ion the fuel lever

as required to maintain a constant engine speed. The actuatcr is operated by a DC

signal from the control unit.

D. Miscellaneous Equipment

ln addition to main components, the system requires wiring, actuata-to+peed

control lever I in kage , mounting brat kets , etc .

3. Operation

From an operator’s viewpoint, operation of the electric-hydraulic governor is very s imple.

To give the governcr system full control of engine speed, it is only necessary to apply

12-V DC to the control box by operating a switch as instructed in the basic generator

set manua I.

4. Maintenance

A. General

To make certain the governor system is readyfor operation at all times, it must be

inspected and checked systematically, and regularly, so that defects may be dis-

covered and corrected before they result in failure of the equipment.

B. Inspection

A periodic inspection schedule should be established and maintained. Throttle

linkage should be checked at least every two weeks, or after each 100 hours of

operation.

(1) Check security of all linkage attaching and adjusting hardware.

(2) Check all electrical connections and leads.

C. Lubrication

No lubrication is required.

D . Per iod ic Ma inte nance

Other than irapections and checks described above, no periodic maintenance is

required .

5. Adjustment

A. General

The magnetic pickup and control box have criticai adjustments which can affect

engine perfmmance and therefore generator output, Actuator-to-fuel control

lever adiustment can also affect engine perfarmance .

1

May 24/76

When the srtem is checked, and/cr adjusted, a’definite sequence of procedures

should be followed.

First - Check cx adjust actuator linkage.

Second -Check or adjust magnetic pickup.

Third -Check or adjust control box.

B. Actuator Linkage Adjustment

(1) General

Exact adjustment instructions such as effective length of actuator-to-fuel control

lever rod assembly, cc which hole in actuator lever to attach ball joint cannot

be determined because of slight variations in brackets, meuntings, and engine

performance character ist its. However, definite rules and procedures can be

established as follows :

(a) Adjust linkage to use the FULL TRAVE L of actuator lever.

(b) Linkage must move engine fuel controi lever from FULL IDLE to FULL

SPEED position, or VERY CLOSE to FULLSPEED pasition to allow engine

to pull 125% load.

(c) On self-propelled units, make certain that accelerator linkage dces not

interfere with free operation of actuator linkage through its full travel

from IDLE to lULLSFEED position.

(d) Befcre making any adiwtment, observe and note which hole in actuator

lever is used to mount ball joint. tt does not necessarily have to be in the

same hole as shown in illustrations (see Fig. 2 and 3). Rod connection

to fuel control lever should NOT be changed.

(2) Actuator linkage adjustment on Cummins engines

Be sure to read and note General instructions above. Check and adjust linkage

with engine STOPPED.

(a) Be sure levers (3 and 8, Fig, 2) have not slipped on shafts. In ID LE pcs it ion

actuator lever (3) shculd point fcrward and upward at an angle of 15 to 20

degrees. Speed control lever (8) should point forward in a near horizontal

pcs it ion. If a lever has slipped, position correctly and tighten securely.

Page 4

(b) Disconnect ball joint (4) from actuator lever (3). Place both levers (3 and

8) in FULL IDLE position and attempt to connect ball joint (4) at hole in

lever (3) from which it was removed. If connection cannot be made,

loosen nuts (5) and adjust effective length of rod so that connection may

be made. Effective length of rod, measured between ball joint centers, 1

is approximately 7-7/8 inches. May 24/76

(c) Manually operate actuator lever back and forth between FULL IDLE

and FULLSPEED pasitiom. Speed control lever (8) should be moved

freely through its full range between FULL IDLE and FULL SPEED. If

adjustment is unsatisfactory, try another hole mounting in ACTUATOR

lever and readjust rod length.

(d) Tighten all parts securely when adjustment is completed.

(3) Actuate linkage adjustment on Detroit Diesel engines

Be sure to read and note General instructions above. Check and adjust

linkage with engine STOPPED.

(a) Be sure levers (2 and 6, Fig. 3) have not slipped on shafts. In IDLE

position actuator lever (2) should point almcst straight upward at an

angle of about IO degrees toward the rear of engine 9 Speed control lever (6) should point almcst straight outward at an angle of about

10 degrees toward rear of engine . If a lever has s I ipped, posit ion

ccrrect ly and tighten securely.

May 24/36 Page 5

(b) Remove bail joint (3) from actuator lever (2). Place both levers (2 and 6) “*‘.

in FULL IDLE position and attempt toconnect ball joint (3) at hole in lever

(2) from which it was removed. If connection cannot be made, loosen nuts

(7) and adjust effective length of rod so that connection may be made.

Effective length of rod, measured between bail joint centers, is generally

53/8 to 5-3/4 inches .

C . Magnetic Pickup Adjustment

The strength of the magnetic pickupsignal to the control box can be weakened

if the tip of the pickup is too far from the flywheel ring gear. If the pickup is

to be removed for any reason, or if the signal is wak, adjust pickup as follows:

NOTE: Adjustment procedures are the same for Cummins and Detroit Diesel

engines. Thedifference between the two is the location of pickup

in engine f lywhee I h ous ing . :

(1) Disconnect “pull-apart” connects (1, Fig. 4 cr 5).

(2) Loosen nut (3) and remove magnetic pickup (2).

(3)

(4)

(5)

May 24/76

NOTE: Some early units may be equipped with an Amphenol connector

on end of pickup.

Inspect to make certainthe tip is not damaged from contact with the ring

gear teeth (replace pickup if damaged) .

Rotate the engine as required to locate a ring gear tooth directly below

the tapped, pickup mounting hole. An imaginary line should pass through

the center of the mounting hole, the center of a flywhee I tooth and the

center of the flywhee I.

Install the magnetic pickup and thread into the mounting hole until the

tip touches the “in line ” f lywhee I gear tooth.

CAUTION: THE PICKUP TIP MUST BE DIRECTLY OVER A TOOTH

AND NOT BEmEN TEETH WHEN ADJUSTMENT Is

MADE.

Back the pickup outward (counterclockwise) l/2 turn. Hoid the pickup

securely in this position and tighten nut (3). This adjustment will result

in a clearance of approximately 0.028 inch between the pickup tip and

the flywhee I teeth and give an operating AC voltage of 4 V to 8 V at

the control box terminals (S and T, Fig. 7), when the engine is running

at no load and governed speed.

NOTE: As little as 1-V is required for operation of governor control

box. Magnetic pickup voltage does not have to be 4-V to

8-V.

There are three adjustment controls on the unit (see Fig. 6). They are identified

as:

FREQ. ADJUST - Adilsts engine speed and generatcr frequency.

GAIN and STABILITY - Adjust engine response time and stability.

To adjust control unit, proceed as follows:

(1) If the control box is being adiusted fa the first time, set adjustment controis

as folloW.:

FREQ. control - Turn adjusting screw at least 22 turns counterclockwise. This

will positively insure that its adjusted position will be at MINIMUMspeed.

NOTE: 1. A very small screwdriver is required for this adjustment.

2. This control is a 22-turn potentiometer with nostops. The

adjusting screw will slip when the wiper reaches the end of

its trave I in either direct ion.

GAIN control - Loosen locknut and adjust the gain control to its approximate

midrange pc6 ition.

STABILITY control - Loasen locknut and adjust stability control to its full

counterc iockwise pcs it ion.

03) Tighten all adjustment control locknuts.

Start engine and allow it to warm,

Pmition controls as instructed in Generatcr Set Manual to make electric governor

system functional.

Turn FREQ adjusting screw (Fig. 6) clockwise to increase engine speed. When

normal governed operating speed has been reached (2400 RPM fcr Cummins and

2000 RPM for Detroit Diesel engines), the generator set frequency meter will

indicate 40031~.

NOTE: Underfrequency indicating light will be turned ON when operating

below 380-H~.

If the engine becomes unstable before 400 Hz is reached, turn GAIN control

counterclockwise until engine speed stabilizes and adjust FREQ control by turn-

ing clockwise to increase speed or counterclockwise to decrease speed until

400 Hz is indicated on the frequency meter.

Turn GAIN control clockwise until the engine becomes just unstable (surges).

Back the GAIN control slightly counterclockwise until the engine is again

stable.

Turn the STABILITY control slowly clockwise until the engine becomes unstable.

Back the STABILITY control slightly counterclockwise until the engine is again

stable. Then back the STABILITY control counterclockwise TWO graduations.

6. Electric Governor Test Values

A. Signal to Actuator

Check amperage value of the signal to actuator by disconnecting lead at terminal

(B, or D, Fig. 6) at control box terminal board. Connect an accurate ammeter in

the circuit . Current value when operating at governed speed (2000 RPM, 4OO-HZ)

should be 2.1-A to 3.0-A at 4-V to 6-V. At full load, current value should be

0.9-A to 1.3-A HIGHER than no-load value. Voltage should be approximately

4 to 6-V DC at no load.

8. Magnetic Pickup Signal

Connect a high impedance voltmeter to magnetic pickup input terminals (S and T,

Fig. 7) on control box terminal board. The voltage value at governed speed, no

load should be 4-V AC MINIMUM.

NOTE: A signal as low as 1-V is sufficient to operate the control unit

satisfactorily. No voltage indicates the pickup is too far’ from

flywhee I teeth, or it is defective.

B. With engine stopped, the actuatcr arm (1, Fig. 8 or 9) should be in IDLE pmition.

Hold arm (1) in FUILIDLE position and observe clearance at A, between arm (1)

and finger (2). Cl earance should be at least l/16 inch when all components are

in IDIE position.

C. To adjust clearance, loosen locknut (6) and either thread extension rod (4) farther

onto the ccce (7), or back it off, as required’to reposition finger (2) and obtain

a clearance (A) of l/16 to l/8 inch between arm (1) and finger (2).

NOTE : Nut (6) must be tight against finger (2) when checking clearance.

D. Operate arm (1) throughout its full travel to make certain it will not touch any

component inc lud ing finger .

E. Position nuts (3) to limit travel of linkage toward full speed position.

F. Check security of all components.

8, Trouble Shooting

A. General

In trouble shooting the all-electric governor system, check components in the

following sequence.

(1) Make certain that all connecting wiring is good and that all terminals are

properly connected and secure (see Fig. 7).

(2) Be sure actuator linkage has no looseness or Icat motion. Be sure it is free

and properly adiLsted.

(3) Be sure that the magnetic pickup is sending an adequate signal (at least

1 volt) to the control box.

(4) Make certain that the control box is receiving 12-V DC power, and that it is

sending a signal (2.1-A to 3.0-A) to the actuator.

B. Electric Governor Characteristics

The following facts concerning the operation of the electric governor may be

helpful in understanding the system and in determining which unit in the system

is faulty in case of troubles.

(i) The system requires a source of 12-V DC power to the control box.

(2) The system requires a 1-V AC I cr more I signal from the magnetic pickup. 1

May 24/36 Page 13

: I : ‘: ;’

.- ,.

(3) The control box must send a 2.1-A to 3.0-A signal to the actuator at no load,

(4) Assuming other conditions are normal, the actuator will go to, or remain in,

IDE position under the following conditions.

(a) No 12-V DC pov,er

(b) No current from control box to actuator

(c) N:o s’ignal fr om magnetic pickup

(5) The actuator will “surge” under the following conditions:

(a) “Stability” cr “gain” adjustment set too “high”

(b) Actuator linkage loose

(c) Actuator linkage binding
